For those people who have iris that rebloom regularly for them, they
report. And then information is properly recorded. And expectations
of various rebloom in various zones can be relied on. Once in 20
years in zone 4 is not information that can be counted on.

When you check the "rebloom" iris offered by Spring Garden and ilk,
you find that they have used rebloom information from list , sometime
along the process. When checking out some of their listing I found
information such as one rebloomer sold in Canada was recorded as a one
time event, of rebloom in Australia. No other rebloom reported. This
iris (along with many other on their list) will never rebloom in
Canada. Some don't even make it through first year. Many people by
these collections, both in Canada and USA. When they don't have
rebloom they then can give up on rebloomers. Several such comments
on "Iris lovers" recently are very likely from this sort of practice.

So a "once off" rebloom from one iris in one location, when reported
as a reblooming iris can have unwanted effects. Even if it is once
every three years , it gives useful information. Once in 20, of no
value, except to be used as misleading information from the "Spring
Gardens " of the world. And you can bet that they will use it.

May be a matter of neuances, but . . . just because something doesn't
rebloom
in your yard doesn't mean they aren't rebloomers. My opinion.
'Forever
Blue' doesn't rebloom here, but I don't question that it is a rebloomer
. . .

for you and others.

'Victoria Falls' did fall bloom for me

in Alvaton, in the 90's. It grew over 40 inches tall and I quit
counting at
18 buds. Don't think it has done this since. It's my opinion that
it's been

proven to be a plus when breeding rebloomers. It contributed height,

branching and improved flower form. Maybe there was another path?
Maybe even

a better path, but nothing else has proven to measure up.

Subject: [iris] Re: classifying as a Rebloomer
Bloom
triggers for plants are complicated, and you can occasionally get
misfires. A
number of years ago in our area some apple trees bloomed
in fall. But a once
off occurrence. Rebloom yes, but it doesn't make
these apple trees
rebloomers.
Right now I have Victoria Falls in bloom, and on a 50" stalk,
standing up straight and tall. But the only time it has fall bloomed in
over
20 years of growing it. I'm not going to send in a rebloom report
on it as it
is a once off event. About 4 years ago I had a fall bloom
on a clump of Best
Bet. Again a once off event as it also has done
this once in about 20 years.
I'm not going to list them as rebloomers
for me in my zone 4 garden. And
having them listed as zone 4
rebloomers would be inaccurate and deceptive.
Not a behaviour you can
rely on.
On the other hand, my SDB Juiced Up is
reblooming now on several
clumps. I first had rebloom on Juiced Up about
2006, after initial
bloom in 1998. It was interesting, but even if it had a
rebloom parent,
that still didn't make it a rebloomer. But in the past four
years it
has rebloomed three times. I'll now report it as a rebloomer for my
climate zone.
A once off event of rebloom is exciting, and worth noting ,
but
doesn't make that plant a rebloomer for me. I have over the years
have had a good number of oncers put up an out of season or even twice
a
year bloom. these things can and do happen. Doesn't make it a
rebloomer as
far as I'm concerned.
